  • Head for multiple insulation of conductors
    Patent number: 4134715
    Abstract: A unitary head, adapted to attachment to the outlet of an extruder contains main inlet duct for passing hot extruded plastic material to a flow regulator which divides and controls the flow of the plastic material into a plurality of calibrated passages. The calibrated passages terminate at jaws which are adapted to grip and hold dies. The plastic material passes from the calibrated passages into the dies and coats the cable passing therethrough.

  • Laser having a brief discharge between two elongated electrodes
    Patent number: 4135167
    Abstract: The invention concerns a travelling wave laser and has application to the reduction of the divergence of laser beams. The electrodes between which the travelling electric discharge for the excitation of the amplifier gas takes place have a cross-section in the shape of two polished rounded-off points facing each other, so as to prevent spurious reflections of light towards the discharge zone and to reduce the divergence of the output beam which is converged by means of a simple optical system.

  • Device for regenerating zinc
    Patent number: 4132623
    Abstract: The invention relates to a method and device for regenerating zinc for use in electric traction batteries. It consists of putting an alkaline solution of zincate in contact with two electrodes at opposite potentials so that zinc dendrites are deposited on protrusions provided on the negative electrode and so that oxygen is evolved on the positive electrode, said zincate solution being, in a first period, called the deposition period, conveyed towards the ends of the protrusions and at a low speed, then in a second period, called the detachment period, conveyed in the opposite direction and at a sufficiently high speed to detach the dendrites from the protrusions.

  • Motorized drive assembly for a circuit breaker operator
    Patent number: 4131776
    Abstract: A motorized drive assembly for a circuit breaker operator comprising a follower mounted on a free wheeling double helix shaft which extends in the direction of movement of the operator between "TRIP," "RESET" and "ON" positions, the shaft being driven by an electric motor through a disengageable gearset controlled by a solenoid. The follower engages the operator, and upon rotation of the shaft the follower moves in one direction carrying the operator from a TRIP position to a RESET position. At this point, the follower has moved as far as one of the double helices will carry it in that direction, whereupon internally projecting lugs of the follower engage the other helix for movement in the opposite direction to carry the operator from the RESET to the ON position in which the breaker contacts are closed.

  • Charging valve for a fluid pressure accumulator
    Patent number: 4131125
    Abstract: An accumulator charging valve has a housing with an inlet and two outlet orifices respectively connected to the pump outlet, to a fluid accumulator and to an open center hydraulic circuit. A main passage is provided between the inlet orifice and the second outlet orifice, with a movable valve member mounted in the main passage, and operated by a differential piston having a face of smaller diameter exposed to the pressure prevailing at the inlet orifice and a face of larger diameter projecting into a control chamber, forming a resilient variable volume enclosure. A leakage passage is provided between the inlet orifice and a low pressure reservoir and has a first portion with an orifice of restricted cross-section situated between the inlet orifice and control chamber, and a second portion also with an orifice of restricted cross-section situated between the control chamber and the reservoir.

  • Apparatus for collecting fluid seepage in a building structure
    Patent number: 4129967
    Abstract: An apparatus for collecting fluid seepage in a building structure or the like wherein the structure is constructed with generally horizontal slabs having separations therein, such as expansion joints and/or shrinkage cracks, settlement cracks, stress cracks or the like. The apparatus includes first and second elongate barrier strips operably positionable along opposite sides of the separation. A flexible collection sheet is hung from mounting channels on the outer edges of the barrier strips. Drip contour lips are fashioned upon the inner edges of the barrier strips and serve to direct fluid seepage passing through the expansion joint, stress crack, or the like, into the collection sheet.

  • Scroll-type liquid pump with transfer passages in end plate
    Patent number: 4129405
    Abstract: Scroll apparatus for pumping liquids wherein recessed liquid transfer passage means are provided in the end plates of the scroll members. The transfer passage means may be inner passages within the scroll involutes, outer passages outside the scroll involutes or a combination of inner and outer passages. These passages are located and configured to be opened substantially immediately after the orbiting involute wrap has reached that point in its orbiting cycle to define three essentially completely sealed-off liquid zones. These passages remain open at least until the liquid passages between the wraps are sufficiently large to prevent any substantial pressure pulsations within the scroll liquid pump. The scroll liquid pumps may be operated to pump liquid radially inward or outward.
